A little old lady answered a knock on the door one day, only to be confronted by a well-dressed young man carrying a vacuum cleaner.

‘Good morning,’ said the young man. ‘If I could take a couple of minutes of your time, I would like to demonstrate the very latest in high-powered vacuum cleaners . ‘

‘Go away!’ said the old lady. ‘I’m broke and haven’t got any money!’ and she proceeded to close the door.

Quick as a flash, the young man wedged his foot in the door and pushed it wide open. ‘Don’t be too hasty!’ he said. ‘Not until you have at least seen my demonstration.’ And with that, he emptied a bucket of horse manure onto her hallway carpet. ‘If this vacuum cleaner does not remove all traces of this horse manure from your carpet, Madam, I will personally eat the remainder.’

The old lady stepped back and said, ‘Well let me get you a fork, ’cause they cut off my electricity this morning.

After his horrible meal, he went to another house, which was in fact a farm house. He checked the electricity was still on, and then knocked at the door.

He went through his spiel again to the farmer's wife who had answered the door, but said "I no longer have anything to demonstrate with, but with this being a farm, perhaps you have some wheat or something?" The farmer's wife found a sack of wheat, and he took a handful of it and threw it on the ground. However, try as he might, the high-powered vacuum cleaner simply would not clean it up! He got a little frustrated, then looked at the wheat and noticed it was a little damp. He thought for a moment, and as he was thinking he noticed another sack that had been sitting by the radiator in the hallway. He asked the farmer's wife if he could try with that wheat instead.

She rolled her eyes, and said "OK... but this is your last chance". He took some of the wheat from the new sack, and poured it onto the floor, and the vacuum cleaner cleaned it all up without any issues! The farmer's wife was delighted and bought one right there!

The moral of the story is: If at first you don't suck seed, try drier grain.
